The major changes in the international arena since Russia's invasion of Ukraine make Iran a balance between the eastern axis of Russia and China, and the Western axis led by the United States. Therefore, Iran probably feels now that it can raise the price for its signing of the nuclear deal. Iran has announced that it is demanding guarantees from the United States that it will not rescind the agreement it will sign again.
Iran presents its demand on the eve of US President Biden's visit to the region, and his attempt to create a new Middle East. The United States understands that it will be easier to settle the Middle East at will, if it succeeds in reducing Iran's presence as the opposite side of the barricade with Saudi Arabia, the Gulf states and Israel. Iran and Israel, apparently understand that in the international sense the US desire in the Middle East is to drive a wedge between China and Russia and make it difficult for them to forge a valid political axis, with Iran and its satellite countries, which has the power to challenge the Western axis. If America does establish a regional NATO, and does not result in the outbreak of a regional war, it may indeed weaken the Eastern Axis, and perhaps even take out Russia's desire to continue to run over Ukraine facing the West. In this context, it must be said that the Middle East has proven many times, from the dawn of history to modern times, that it never cooperates with dreams. Even if these are the dreams of a world power.
Iran claimed to the Qatari foreign minister who visited Tehran last week that the US was pressuring it to sign an agreement that would not fully serve its long-term interests. This announcement does not clarify whether these interests include uranium enrichment when the agreement expires. The Qatari foreign minister's visit to Tehran took place, according to the Iranians, after he spoke with Secretary of State Anthony Blinken, and passed on US demands to Iran. As mentioned, the Iranians understood from what the Qatari foreign minister told them, that the United States demands that Iran sign the agreement, apparently without removing the Revolutionary Guards from the list of terrorist organizations, as Israel demands.
Which may support the US strategy to weaken the Eastern Axis, by reducing Iran's role in it, is that the Islamic murderous regime in Tehran understands that severing contact with the West, may increase internal unrest within Iran, while cooperation with Vienna may contribute to it in terms of economic growth and industrialization (see report today) as well as in terms of internal peace. Cooperation with the nuclear deal, on the other hand, does not necessarily undermine Iran's attempts to expand into the Middle East, and perhaps vice versa.
